Letters Patent No. 109,926, dated December 6, 1870.

IMPROVEMENT |l\l TUiRBlNE WATER-WHEELS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, RANSOM MONROE, of Hen,dricks Greek, in the eonntyofLuzeru'e and State of Pennsylvania, haveinvented certain new and useful Improvementsiu Turbine Tater-Wheels. ofwhich the following is a specification.

Nature mul Object of the Intention.'

My invention relates to an improvement in turbine water-wheels, andconsists in constructing a waterwheel with spiral issues, the upperdiameter' and the issues at the topof thewheel being greater than theDescription of the Drawing.

Figure l is a vertical transverse section of the invention, cuttingthrough the lines y y inlig. 2, and

showing the portion above the lines y y.

Figure 2 is a horizontal transverse section, euttini;r through the line:t a; in fig. 1, and showing that por- Genera-Z Description.

The wheel A has its bearings in -the beams f and g.: Its diameter isabout two inches greater at its top h than at its bottom t.

l lhe issues B are about one inch larger at the top than at the bottomofthe wheel A.

The sills o, uprights p, girders q, and cross-beams fr, compose theframe-work which supports the 'wheel A and a portionof the iluine C.

dis a covering placed over the flume C.

o are key-bars that pass between the girders q and the Covering d, toprevent the water from pressing the covering l against the shoulder 7.1.

.lhewheel -is really a screw, and the Iweight ot' water resting on thescrew gives it more power than the force of the water does. v

The issues being,` the full length of the wheel, the water is in fullforce the full length ofthe wheel being smaller at the bottoni than atthe top causes a lirnr pressure ofthe wat-er on the paddles4 between theissues.

The ykey-hars e and the covering d can be removed and the wheel takenout for repairs when necessary.

Claims.

I claim as lmy invention- 1. lhe Water-wheel A, Whose diameter isgreat'- er at thev bottom than at the top, 'provided with spiral issuesBv B, relatively larger at thetop than at the bottom, thus preservingthe outer periphery of4 the buckets `in a perpendicular line,substantially' as and for the purpose set forth.

2. 'lhewheel A, provided with shoulder It, in com# bination withcoverings d d, and key-bars e' erall arranged as and for the purposese't forth. In testimony that I clairn the foregoing improvement inturbine-wheels, as above described, I have hereunto set my hand and sealthis 13th day of July, 1870.
